Hi guys, hoping this is the right forum.
I've got a Maths assignment I'm working on and I've completed the whole paper save one question. I'm really not sure how to go about doing this - here's the question:
5 = 0.4i1 + 1.8(i1-i2)
12 = 2.4i2 - 1.4(i1-i2)
Hope that's readable. I've tried substituting, but that (i1-i2) really throws me off. Anybody able to help?
Thanks in advance.
